A walkathon is a common fundraising event that many nonprofits host to raise money and get people up and moving. A dog walkathon is the same thing but with adorable pooches!
Of course, people can still participate, but they can bring their (leashed) dogs along to keep them company while they walk. You should make sure to have water stations set up for humans and pups alike, especially if you host your dog walkathon on a really hot day!
You can charge an admission fee to raise money, but you can also sell shirts, caps, water bottles, and leashes to raise more.
With the proper promotion, your dog walkathon can be a major hit. Try it next summer to raise money!
